Front

What is a Box and Whisker Plot?

Back

A Box and Whisker Plot is a graphical representation of a dataset that shows its minimum, first quartile (Q1), median, third quartile (Q3), and maximum values.

Front

What does the minimum value represent in a Box and Whisker Plot?

Back

The minimum value is the smallest data point in the dataset.

Front

What does the maximum value represent in a Box and Whisker Plot?

Back

The maximum value is the largest data point in the dataset.

Front

What is the median in a Box and Whisker Plot?

Back

The median is the middle value of the dataset when it is ordered from least to greatest.

Front

What are quartiles in a Box and Whisker Plot?

Back

Quartiles divide the dataset into four equal parts: Q1 (25th percentile), median (50th percentile), and Q3 (75th percentile).

Front

How do you find the upper quartile (Q3)?

Back

Q3 is the median of the upper half of the dataset, representing the 75th percentile.

Front

What does a Box and Whisker Plot show about data spread?

Back

It shows the spread of the data by displaying the range and interquartile range (IQR), which is the distance between Q1 and Q3.

Front

What is the interquartile range (IQR)?

Back

The IQR is the difference between the upper quartile (Q3) and the lower quartile (Q1), indicating the range of the middle 50% of the data.

Front

How can you identify outliers using a Box and Whisker Plot?

Back

Outliers are typically identified as data points that fall below Q1 - 1.5*IQR or above Q3 + 1.5*IQR.

Front

What does a 'spread out' Box and Whisker Plot indicate?

Back

A 'spread out' Box and Whisker Plot indicates a larger range of data values and greater variability in the dataset.
